Better Stack Koa client

Start logging in 3 steps

1. Install

Install Logtail Koa NPM package:

npm install @logtail/koa

2. Setup

Set up Logtail client and attach it to Koa instance:

const Koa = require("koa");
const { Logtail } = require("@logtail/koa");

// Create new Koa instance
const koa = new Koa();

// Create new Logtail client
const logtail = new Logtail("$SOURCE_TOKEN");

// Attach Koa to enable HTTP request logging
logtail.attach(koa);

3. Start logging 🎉

All HTTP requests handled by Koa will be logged and sent to Better Stack.

Ensure that all logs are sent to Logtail:

logtail.flush()

You should see your logs in Logtail → Live tail .

Additional information

How the middleware works

Successful requests

Successful requests end with a 2xx or 3xx status codes and do not throw any errors. They are logged to Logtail using Info log level .

4xx status codes

Requests with 4xx status codes are considered warnings. Such requests are logged to Logtail with Warn log level .

5xx status codes

Requests with 5xx status codes are considered errors. Such requests are logged to Logtail with Error log level .

Uncaught errors

Unhandled errors are caught by Logtail middleware. The errors are logged to Logtail with Error log level .

Additional logging

With Logtail Koa client you can use debug(), info(), warn(), and error() methods just like with Logtail JavaScript client.
